Problems solved by technology

[0004] For the germs and their hazards in the branches, at present, they are mainly controlled by scraping off the diseased spots and old warped skins of the branches, and then applying or spraying pesticides. The workload is relatively large, and a large amount of pesticides are still required

Embodiment 1

[0016] In order to control branch ring disease (coarse skin disease) of Fuji apple, crabapple was selected as the base stock 1, and cockscomb apple was selected as the middle stock 2. In the spring of the first year, rootstock seedlings of crabapple were cultivated, and cockscomb apples were grafted at 2-4cm above the ground in fall of crabapple; in autumn of the second year, at 40-60cm of the branches of crabapple, from different directions, Fuji apples were grafted. 3-5 buds 3 are grafted on the branches of crabapple; in the third year, Fuji apple buds 3 germinate branches 4, and in autumn, the Fuji apple plant resistant to rhizome is composed of three parts of crabapple, cockscomb apple and Fuji apple Breeding complete.

Embodiment 2

[0018] In order to control Fuji apple branch ring disease (coarse skin disease), select the adult cockscomb apple tree with normal growth, and in spring, according to the known method of "high grafting and replanting" of fruit trees, Fuji apple is high-grafted on the cockscomb apple tree.

[0019] The present invention utilizes the disease-resistant intermediate stock (2) to improve the disease resistance of cultivars and the whole plant, reduces the workload of scraping and curing fruit tree branch and trunk diseases, reduces the amount and frequency of use of pesticides in orchards, and is beneficial to the pollution-free production of fruits .

Abstract

The invention discloses a method for strengthening disease resistance of a fruit tree by applying an interstock, which is mainly characterized in that a locally appropriate and strongly resistant fruit tree stock is taken as a rootstock (1), a variety or a type which has strong resistance to diseases to be controlled is grafted on the rootstock as a disease resistant interstock (2), then a variety (3) to be cultivated is grafted on the interstock, thus a disease resistant plant is composed of the rootstock (1), the disease resistant interstock (2) and the cultivated variety (3). By adopting the disease resistant interstock (2), the method for strengthening disease resistance of a fruit tree by applying the interstock improves the disease resistance of the cultivated variety and the whole plant, reduces the workload of scraping and treating diseased fruit tree branches, and decreases the amount and times of applying pesticides to an orchard, which is beneficial to the nuisance-free production of fruits.

Description

1. Technical field [0001] The invention relates to an agricultural control method for fruit tree diseases, belonging to the field of agricultural disease and insect pest control; in particular, it relates to a method for enhancing the disease resistance of fruit trees by using an intermediate stock. 2. Background technology [0002] For the production of pollution-free agricultural products, the use of agricultural methods to prevent and control pests and diseases is advocated, such as selection of varieties resistant to diseases and insect pests, rational crop rotation and intercropping, scientific fertilization, etc. The resistance is not strong, and the effect is not very satisfactory. Therefore, it is necessary to continuously develop new agricultural control methods. Compared with chemical control and biological control methods, agricultural control methods are safer and more in line with environmental protection requirements, but there are few technological inventions ...
